Mayonnaise vacuum emulsifying homogenizer

The mayonnaise vacuum emulsifying homogenizer is a device specifically designed for the production of emulsified products such as mayonnaise. It is mainly based on the principles of emulsification and homogenization. Emulsification is the process of forming a stable emulsion by adding an emulsifier to two immiscible liquids, such as oil and water, under the action of mechanical force. In the production of mayonnaise, the oil phase and the water phase (containing components such as vinegar and egg yolks) are mixed with the help of emulsifiers (lecithin in egg yolks is a natural emulsifier).

2. Homogenization is to further refine the dispersed phase particles, making the emulsion more stable and fine. The vacuum emulsifying homogenizer operates under vacuum conditions. On the one hand, it can prevent air from being mixed into the emulsion during the stirring process, thus avoiding oxidation and foam formation. On the other hand, a vacuum environment helps to enhance the efficiency of emulsification and homogenization, resulting in better product quality.

Emulsifying tank: This is the main part, usually a stainless steel tank with a jacket. The jacket can be filled with hot or cold water to control the temperature during the emulsification process. Inside the tank, there are stirring devices, such as anchor agitators, frame agitators or multi-layer paddle agitators, etc., which are used for mixing the oil phase and the water phase.

2. Homogenizer: It is a key component and generally adopts a high-speed rotating rotor and stator structure. When the material passes through the homogenizer, under the combined effects of the powerful shearing force, centrifugal force and hydraulic collision generated by the high-speed rotation of the rotor, the dispersed phases such as oil droplets are refined, forming uniform tiny particles.

3. Vacuum pump system: It is used to extract the air inside the emulsifying tank and create a vacuum environment. It includes components such as vacuum pumps, vacuum pipes and valves to ensure that the vacuum degree inside the tank meets the set requirements.

4. Control system: It can precisely control parameters such as emulsification and homogenization time, rotational speed, and temperature. Operators can set different working modes through the control panel, such as stirring speed, homogenization speed and time, heating or cooling temperature, etc.

1. Raw material preparation: Prepare oil, water, egg yolks, vinegar, sugar, salt and other seasonings in accordance with the proportion of the recipe. Usually, the aqueous phase raw materials (such as water, vinegar, egg yolk liquid, etc.) are first put into the emulsifying tank.

2. Vacuuming: Start the vacuum pump system to extract the air inside the emulsification tank to achieve a certain vacuum degree. The general vacuum degree is between -0.08 MPa and -0.09MPa.

3. Emulsification and stirring: Turn on the stirring device and slowly add the oil phase. The stirring speed is determined by the formula and product requirements. At the beginning, the speed can be slightly slower to prevent the rapid accumulation of the oil phase. As the oil phase is continuously added, the stirring speed should be gradually increased.

4. Homogenization treatment: After all the oil phase has been added, start the homogenizer and carry out the homogenization operation. The homogenization pressure and time also need to be determined based on the characteristics of the product. For instance, for mayonnaise with a high demand for a delicate texture, the homogenization pressure might be set higher and the time would be relatively longer.

5. Discharge and packaging: After homogenization is completed, the vacuum is removed, and the product is discharged through the discharge port for packaging. The packaging form can be in bottles, bags or barrels, etc., depending on market demand.

1. High product quality: Due to emulsification and homogenization carried out in a vacuum environment, the mayonnaise produced has a fine texture, good taste, and is not prone to oxidation, thus extending the product's shelf life.

2. High production efficiency: It can quickly mix and homogenize the oil phase and water phase, significantly reducing production time compared to traditional stirring methods. Moreover, it can precisely control the parameters during the production process, ensuring the stability of product quality and is suitable for large-scale industrial production.

3. Versatility: Besides mayonnaise, it can also be used to produce other emulsified products, such as salad dressings, creams, lotions, and various other cream and ointment products.

1. Cleaning work: After each use, the emulsifying tank, homogenizer and other components need to be thoroughly cleaned. It can be rinsed with warm water, detergent, etc. For stubborn residual materials, special cleaning solvents can be used. After cleaning, make sure the interior of the equipment is dry to prevent bacterial growth.

2. Component inspection: Regularly inspect the wear conditions of easily worn parts such as the rotor and stator of the agitator and homogenizer. If severe wear is found, it needs to be replaced in time to ensure the normal operation of the equipment. At the same time, check the sealing performance of the vacuum system to ensure that the vacuum degree can meet the requirements.

3. Lubrication and maintenance: Regularly lubricate the moving parts of the equipment such as bearings and motors to extend the service life of the equipment. Use the appropriate lubricant and operate in accordance with the requirements of the equipment manual.
